Image received here of VK3JTM on 1296 MHz WSPR. In this image you see Tim's main tropo signal is very Fat at 13 Hz wide, some possible scattering effect.Also notice the high doppler rate Aircraft reflected signal thats ran across the screen, peaking S5 on the meter where it crossed the main signal. You can see also, particularly on the WSPR display that there is excessive drift on the main signal, this would stop any decode chance (as well as the signal spread).Path length is 428 km.

Now that my rig is locked to GPS reference, I'll be able to send out stable signals on 1296 WSPR.

1296 MHz WSPR operation, is going to be a bit of an individualised sked operation I think, due to narrow beamwidths and weak sigs. There could be exceptions though, such as in the Geelong and Melbourne areas where there may be a few stations gathered in close proximity.

I'll be interested to hear from stations who wish to give it a try. If your rigs not locked to a reference, its probably going to have to much drift, but I hope some stations just may care to go in RX mode only and upload reports.From here I have a limited azumith range, covers from just east of Melbourne, VK3RXX beacon area is about the comfortable limit, then can cover all directions back towards Adelaide and reasonably comfortable to VK5LA or Mildura.

Due to limitations of some of the WSPR programs not being able to upload 1296 MHz freq reports, we have changed bands on the program to report at 432.022 dial freq which should show up as something like 432.023 (for 23cm) in the 70cm database section.

But we are still on 1296.110 radio dial.

The tropo is pretty flat but we have gotten a few through amidst sorting the program issues -

I've been advised by Jorgen OZ7IT, that to resolve the error when uploading spots to the 1296 database. When u select Band - Other, and type in 1296.110 dial freq, you must first put in a Space in before u type in 1296.110.Will have to give this a try next time.
